Abstract (en)

[origin: US2005215735A1] A process for polymerizing and copolymerizing cyclic olefins, such as, norbornene is disclosed. The disclosed process uses a catalyst complex that exhibit a high activity for the polymerization and co-polymerization of cyclic olefins and improved stability toward heat, oxygen and moisture.
